Abstract

Vynález se týká teplotního aktuátoru obsahujícího pohyblivé prvky tvořené kovy s tvarovou pamětí a jeho podstata spočívá v tom, že je tvořen soustavou alespoň dvou za sebou uspořádaných SMA prvků (1) aktivovaných různými transformačními teplotami. SMA prvky (1) mají kladný a/nebo záporný posuv, jsou od sebe odděleny spojovacími prvky (2) a jsou tvořeny tyčovitými a/nebo ohybovými prvky a /nebo spirálovými (pružinovými) prvky.The invention relates to a temperature actuator containing movable elements formed by shape memory metals, and its essence is that it is formed by a system of at least two SMA elements (1) arranged one behind the other, activated by different transformation temperatures. SMA elements (1) have a positive and/or negative displacement, are separated from each other by connecting elements (2) and are formed by rod-like and/or bending elements and/or spiral (spring) elements.
